I played(rather attempted to play) a Yamaha CVP 701 at our local music store. The piano had a very nice action, but from what I could tell, didn't have much more electronics built into it than a DGX 650 that I also played at roughly 1/6 the cost of the CVP.

The screen on the CVP was tiny.

Playing the CVP was, for me, a bit like playing the DGX 650 in a real nice wooden case..??

I'm probably not the best to evaluate as I really don't know pianos...but still.
